BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT

[0001] 1. Field of the Invention

[0002] The present invention relates to a sewing machine and the system thereof, and more particularly relates to operating the sewing machine under control of external information while machine control information is outputted.

[0003] 2. Prior Art

[0004] According to the conventional sewing machine, a pattern to be stitched is optionally selected among a plurality of different patterns in reference to the pattern data or indication data which are stored in the sewing machine. It has been proposed that an external memory having pattern data stored therein is removably connected to the sewing machine so as to stitch new patterns. However, as the external memory has no indicating means such as a display, the machine user can not know the contents of the memory until the same is connected to the sewing machine. Further, the machine user has to know the contents of the internal and/or external memories at a limited area of display which is arranged in a limited space of the sewing machine frame and often fails to show thereat a sufficient amount of information as required by the user. Further, it has been proposed to read out the pattern data from a plurality of external memories, capacity of which is limited respectively, so as to form a pattern in combination of different patterns. In this case, at most two memories are allowed to be connected to the sewing machine. It has, therefore, been very troublesome to exchange the external memories in case the patterns to be combined are stored in many memories, for example, in more than four memories. Further, as an external environment means, a computer has been proposed to be connected to the sewing machine. this is, however, to simply give instructions on the basis of data and is not a part of sewing machine system for cooperating with the sewing machine. Namely, the computer fails to renew and indicate the content of control for the sewing machine.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0024] The invention will be described in detail in reference to the embodiment as shown in the attached drawings.

[0025] In FIG. 1 the reference numeral 1 represents a sewing machine 1 with an embroidery stitching function and the system thereof The sewing machine is provided with CPU (Central Processing Unit) 5 having a drive motor (not shown), first and second control motors 3, 4 (not shown) connected thereto, the drive motor being provided to drive the sewing machine for stitching operation, first and second control motors being provided to control the movement of an embroidering frame in X-direction and Y direction respectively, the embroidering frame having a cloth held thereon to be stitched.

[0026] The reference numeral 6 denotes a first memory 6 having pattern data and indication data stored therein and connected to the CPU 5. The reference numeral 7 denotes a second memory having control system programs store therein for controlling the operation, indication of the sewing machine and controlling the input and output of information and connected to the CPU 5. The reference numeral 8 denotes a third memory for storing as renewed at least one of the pattern data, the indication data and control data and connected to the CPU 5. The control data includes the contents for controlling the sewing machine and the data for registering the contents of indication and the initial conditions of the sewing machine selected by the user or machine operator and the conditions to be registered.

[0027] The reference numeral 9 denotes a display arranged at a front side of the sewing machine 1 for indicating thereat the pattern data and various messages and connected to the CPU 5.

[0028] The reference numeral 10 denotes a plurality of external memories which may be removably attached to the sewing machine 1. The memories 10 have stored therein a plurality of pattern data and indication data which are different from those sorted in the first memory 6. The memories 10 may be selectively attached to the sewing machine and connected to the CPU 5. The memories 10 may have stored therein control programs in addition to the pattern data and indication data. The control programs may be memorized in the third memory 8 so as to change the contents of control.

[0029] The reference numeral 11 denotes an input/output means connected between the sewing machine 1 and an external environment means 12. Preferably, the input/output means may be removed while power is supplied in case the external environment means 12 is a personal computer. Precisely, the input/output means 11 is the USB by use of the USB cord.

[0030] Preferably, the external environment means 12 is a personal computer including a large sized indicating means (not shown), a data reading means 14, a combining means 15, a memory 16 for storing therein combined data and inputted data and a connecting means 18 for connecting the external environment means 12 to an external information net means 17. Preferably, the external information channel net means 17 is a public or personal channel including internet and cable.

[0031] Operation is as follows:

[0032] Power is supplied to the sewing machine 1 and the external environment means 12 to activate the same respectively, and the two members are connected to each other by the input/output means 11. The combinations of patterns incorporated in the sewing machine 1 are given the ID's and register numbers of users or machine operators and are stored in the third memory 8 and are further outputted to external environment means 12 to be stored in the memory 16. The contents stored in the memory 16 may be optionally read out to be used for stitching operation.

[0033] Further, the contents to be indicated at the display 9 of the sewing machine 1 and the size of indication and the color setting information may be stored in the third memory 8 and may be further outputted to the external environment means 12 to be stored in the memory 16. The contents stored in the memory 16 may be optionally read out. The contents of the machine control data may be changed or renewed by the control programs from the external memory 10 of the sewing machine 1 and/or from the external environment means 12. The prior contents before being changed or renewed may be recovered because the same may be stored in the memory 16 of the external environment means 12. The contents of data may be stored per pattern, per stitching operation, per user or per machine operator, and the stored contents may be optionally read out and transmitted to the sewing machine 1 to change or renew the setting contents of the sewing machine 1.

[0034] The contents of embroidery stitching operation, the contents of preparation for setting information, the contents of the next process, the information for time elapse, remaining time, finishing time, a finished pattern anticipated and so on may be indicated and confirmed at the display (not shown) of the external environment means 12 one after another in accordance with the information from the sewing machine side.

[0035] The contents of the plurality of external memories 10 may also be confirmed at the display (not shown) by way of the sewing machine 1 or by reading out the same by a data reading out means of the external environment means. Further, these contents of plural external memories may be held as indicated at a single display so that these may be selectively designated and so that, as to the designated patterns including specifically combined patterns, the pattern data and indication data may be transmitted to the sewing machine side with the selecting codes given thereto respectively, so as to be stored in the third memory 8. In this way, the contents of plural external memories 10 may be stitched without exchange of the external memories 10. Further, since the external environment means 12 is independent from the sewing machine 1, the contents to be subsequently stitched may be designated in combined arrangement.

[0036] Further, the sewing machine may be operated by the contents in specific combinations and compilations stored in the external memories 10 by use of the data writing means 20 of the external environment means 12 instead of using the connecting means 18.

[0037] Further, the sewing machine 1 may be operated under control of the external environment means 12.

[0038] Further, the embroidery stitching operation may be performed under control of the pattern data, indication data, control program data, combined data and so on which are stored in the memory 16 as downloaded from the external information channel net 17 through the connecting mans 18 and the external environment means 12 and transmitted to the sewing machine 1. In this connection, the download may be systematized to impose expense on the user in contract with an external information supplier on the basis of the content of information supplied and the number of times that the information is supplied.

[0039] As is apparent from the above description, according to the invention, an external environment means having a display may be provided in connection with the sewing machine to enable the machine user to confirm the information stored in the external memories as well as in the sewing machine, wherein a pattern or patterns in combination may be optionally compiled as partly deleted or added irrespectively of the pattern information stored in the sewing machine and in the external memories. Thus the confirmed pattern information may be transmitted to the sewing machine so that the sewing machine may be operated under control of the confirmed pattern information. Further according to the invention, the external environment means may be connected to an external information channel so that new information may be obtained at a real time:
